7 Claims. (Cl. 91-44) This invention relates to improvements in paraffining machines, and more particularly for impregnating paper bottles inside and outsidepaper bottle making machine which forms the.

subject matter of a separate application; to -provide an apparatus which will take care of the paramning of the bottle as it passes out from the paper bottle making machine and brings such bottle completely paraffined directly to a bottle filling machine; and to obtain other advantages and results as may be brought out in the following description.

In the drawings:

Fig. 11 is a sectional detail of the atomizer nozzle.

As seen in the drawings, the reference numeral I5 is the main driving pulley of the paper bottle making machine, Hi the delivery end only of which is shown. I! is the connecting bar to the rack gear which is pivoted at |8 asshown in Fig. 2. I9 is a link bar pivoted at 20 on the connecting bar I1 and is attached at the oppo site end by a pivot 2| to a bar 22 for controlling the doors and parafilne supply.

I have not shown the rack gear as itforms no part of this invention. I may say, however, that this rack gear is utilized'in the paper bottle machine forming the subject matter of a separate application controlling the movement of the winder, turrets and cooperating mechanism.

The numeral 23 is the frame of the paraifine machine having an extension bracket 24. 25 is a heating chamber which is supported on a supplemental frame 26 upon which is contained a heating element 21. The chamber is a threesided chamber with open ends, and is designed for a purpose which will hereinafter appear. 28 is the pump chamber which is supported on the frame 23 and is preferably rectangular in cross section. 23 is the parafiine pump which is shown in the broken away portion of the chamber being driven by spindle 30 connected to electric motor 3| supported. on the frame 23 asindicated. 32 is the parafiining chamber which is provided with a cover 33 which may be removed to disclose the interior of the chamber for inspection purposes. The chamber 32 is supportedv on top of the pump chamber 28 and is provided with laterally extending chambers 34, one at each side as indicated in Fig. 3. 35 are a pair of doors located in suitable guide-ways 36 and 37 at the top and bottom respectively. 38 are a similar pair of doors located in suitable guideways 39 and 40. The doors 35 are located at the entrance end of the bottles to be paraffined and the doors 38 at the exit end.

In order to carry the bottles to and through the chamber 32, I have provided the endless carrier chain arranged in pairs 4|, 4| and carried at the end by sprocket wheels 42, 42 suitably journalled in bearings in the paper bottle making machine as indicated in Fig. 1. The chains 4|, 4|, pass over sprocket wheels 43, 43 journalled in suitable bearings 44 in the bracket 45 secured to the frame 23 at the opposite end, and also over the guiding sprockets 41 and 48 and journalled in the frame 23 beneath the pump chamber 28.

The carriers 4|, 4|, carry suitably attached to the links thereof, the'bottle supporting rings 49 which are located at equal distance apart as indicated in Fig. 2.

The carrier chains 4|, 4| with the supporting rings 49 pass through orifices 50 and 5| in the doors 35 and 38 respectively when such doors are closed.

In order to provide for the supply of parafline in a liquid state to the chamber 32, I provide the supply pipe 52 as indicated in full lines in Fig. 4 and in dotted lines in Fig. 3. The pipe 52 is provided with branch pipes 53, 53, one at each side which extend up into the lateral chambers and incline downwardly through them near the top into the casings 54 having anend opening 55 opposite the ends of atomizer nozzle 56,which preferably are of the type shown in Fig. 11. The casings 54 are provided with bottom orifices 51 designed to carry the surplus drip from the atomizer casing 54 down through the chamber 32 into the chamber 28 when the valves are closed.

The supply pipe 52 also has a central atomizer nozzle 58. The side atomizer nozzles are designed to impart a fine mist on the exterior of the, bottle and thoroughly permeate the paper, and the central atomizer 58 is designed to likewise impart a similar misty film of paraffine to the interior of the bottle, which is upside down.

59 is a spindle journalled in the brackets 80 and is secured on the frame 23. The spindle 59 carries a rachet wheel 8| which is engaged by a pawl 82 as shown in Figs. 1 and 2. The pawl 82 is carried on the. end of bar 63. 84 is a gear pinion secured on the spindle 58 and meshing with a gear pinion 85 carried on the spindle 86 journalled in the bracket 80. 61, B'Iare sprocket wheels secured on the spindle 88 and carrying the endless sprocket chains 68, 68, which are provided with bottle supporting rings 88 at equal distance apart. The endless sprocket chain 88, 88 extends over sprocket wheels I0, I0, at the opposite end. The sprocket wheels I0, 10 are secured on the spindle 'II journalled in bearings I2 I secured to the bracket 24.

The bar 83 is pivotally secured to a detent 13 attached to the bar 22 and when the bar 22 has imparted to it its outward and inward movement, the bar 83 .has imparted to it a step by step movement which through the pawl 82 and the ratchet wheel 8| impart a like movement to the sprocket chains 4|, 4|, carrying the bottle supporting rings.

The bar 22 has connected to it a bearing lug I4 which is stationary, a further lug I5, secured to the bar 22 by screw I6 which extends through a slot TI in the bar 22 I8 is a rod secured at one end in the bearing lug I5. The opposite end of the rod I8 extends slidably through the lug I4 and is provided with a stop pin "I8. 80 is a spiral Y spring which encircles the bar 18. The normal tendency of the spring is to force the bearing lug I5 towards the end of the slot I7 remote from the bearing lug I4. 8I is a guiding plate secured to the bar 22 and is provided with a guiding groove as indicated in dotted lines through which extends a bar 82. The bar 22 is provided with an inclinedblock 83 with which a detent 84 is designed to engage and ride upon as particularly shown in Fig. 7. 85 is a bracket secured to one end of the bar 22 and through which the end of a rod 88 extends. 81 is a plate secured to the bar 22 above the bracket 85 and is provided at one end with a cam groove 88, one side of which is straight and the other arc-shaped. The cam groove 88 is provided with a spring-pressed controlling pawl 89 which closes one end of the straight side of the cam groove normally. 80 is a block located on the rod 88 and provided with a pin head 9| which extends into the cam groove as clearly shown in Figs. 6 and 7.

The rod 88 has an arm 82 secured to it and pivotally connected by a link 83 to a pin 04 on one of the doors. The rod 88 connected to the bar 22 extends rearwardly to the back of the parafline chamber 32 and has an arm 85 which is connected by a rod 98 to a link 81 and connected to an arm 98 attached to a rod 99 located in bearings I00 on the opposite side of the parafline chamber 82 to the bearing IOI on the opposite side. The rod 88 has an-arm I02 which corresponds to the arm 82 and is connected by a link I03 to a pin I04 on the other door 35. In short, the parts I02, I03, and I04 correspond to the parts 82, 93, and 94, and are designed-to act in unison to open and close the doors 85. These latter parts are duplicated at the rear end of the paraffine chamber 32 so that when the parailine chamber 32 is opened at the front end to let in a bottle, it is likewise opened at the rear end to let out a bottle, and between times the doors are closed to make a completely closed chamber during the paraflining process.

The above parts are operated though the bar 22, the rod 88, the block 90, the pin 9| operating in the cam groove 88 as indicated in dotted lines in Fig. 5. The pin 9| passing through the straight portion of the groove to close the doors and the arc-shaped portion to open them as the bar 22 is moved backwards and forwards.

The bar 82 shown in Figs. 6 and 7 extends through a slot 34' in one of the side chambers 34 and is bent downwardly inside the chamber where it is connected to a U-shaped bar I05 which carries gate valve I08 opposite the central atomizer 58. The bar I05 has pivotally connected to the top of the same, link I01 which is pivotally connected to the double gate valve I08 by the link I09 which is designed to close the two nozzles 58 located at the side of the paraflining chamber 32. It will, of course, beunderstood that the link I01 and the link I09, and-the gate valve I08 are duplicated to close the nozzle 58 at the opposite side of the parafline chamber as indicated by dotted lines.

The bar 22 at the same time that it is operating with the rod 88 and its co-acting parts so as to open and close the doors at the end of the parafline chamber, likewise co-acts with the bar 82 to close the nozzles by the gate valves when the doors are open and to open the gate valves when the doors are closed.

When the bar 22 moves forward; the lug I5 engages the bar 82 and carries the bar 82 with it through the tension of the spring 80. As the bar 82 is carried forward, it will consequently open the gate valves, and as the forward movement of the bar 22 is continued, the inclined block 83 comes in contact with the detent 84 and raises the bar 82 out of engagement with the lug I5 and consequently the spring 80 will extend to its full extent and the gate valves will return to their closed position by their own weight.

It will be noticed that the paper bottles are carried in the reversed position in the rings 48 of the carrier chains 4 I, 4I and in order to place them in their proper position at the filling machine,they must be turned right side up, and to efiect this, I have provided in proximity of the discharge end of the carrier chains 4|, 4|, a dumping chute I In which is secured to the bracket by metal straps III as shown in Figs. '1 and 2. It will be seen in reference to these figures that the chuteis at an incline and as the paper bottle passes over the incline of the chute will cause the bottle to fall into an inclined and finally vertical position as shown by the bottles dotted in to the left of Fig. 1.
